Question

Write given statement using numbers,literals and sign of basic operations.State what each letter represents.

The perimeter of a rectangle is two times the sum of its length and breadth.

Answer 1

Step 1 : Defining the variables

Let Perimeter of a rectangle be $P$

Let length of a rectangle be $l$

Let breadth of a rectangle be $b$

Step 2 : Finding Algebraic Expression

sum of length and breadth = $l+b$

Two times the sum of length and breadth = $2(l+b)$

The perimeter of a rectangle is two times the sum of its length and breadth.

$\Rightarrow P=2(l+b)$

Hence, the answer is $P=2(l+b)$
